Every driven past the Doughnut and wondered if you'd make the cut as a spy? Dreamt of being a GCHQ worker?

Following the Cheltenham based Government Agency's first foray into quiz books the boffins of Benhall have been busy on a new set of brainteasers.

The book offers a huge range of new puzzles, with even more at the much needed ‘easy’ level, for those of us who are more beginner than aspiring intelligence officer or cryptic wizard. And with that little more practice, and tips on how to think like a codebreaker, people might discover that they can crack the most complex puzzles that Britain’s most brilliant minds are capable of creating.

GCHQ base in Cheltenham

Alongside authentic entrance exams, and a number of new puzzles, the book also includes anecdotes about the people, technology and partnerships that are central to GCHQ’s mission. Readers will learn about the power of teamwork, feats of ingenuity, and how the men and women of GCHQ have tackled the seemingly impossible to keep the country safe for 100 years.

“We were delighted with the success of our first puzzle book, which raised over £330,000 for the Heads Together campaign, an important cause to change the conversation around mental health. To mark our Centenary next year in 2019, we have created a new puzzle book celebrating our 100-year history of keeping the country safe.”

“We couldn’t be more delighted to be publishing another book of puzzles from GCHQ, particularly as part of such a momentous anniversary for the organisation. The 2016 book was the Christmas stocking filler of choice and we’re hoping that this new batch will be as fun, mind-bending and rewarding as before.”

The GCHQ Puzzle Book 2 will be published by Michael Joseph on 18 October 2018, just in time for the Cheltenham Literature Festival.
